摘要： The invention relates to a method and to a device for measuring speed in a contactless manner, comprising a proximity sensor (3) which operates according to the eddy current principle. The proximity sensor (3) comprises an inductor (4) and a parallel mounted capacitor, which form an oscillating circuit (6) which can be excited from the outside. The resonance frequency of the oscillating circuit (6) undergoes a detectable modification when a measuring object approaches the proximity sensor (3). With respect to a possible constant sensitivity of the measuring speed for a plurality of different geometeries of the object which is to be examined, the invention is characterised in that the resonance frequency of the oscillating circuit (6) and/or the excitation frequency of the oscillating circuit (6) is influenced in such a manner that the oscillating circuit (6) is always excited with the resonance frequency or with the frequency close to the resonance frequency. Deviations of the frequency of the oscillating circuit from the frequency of the excited oscillator are detected by a phase comparator. A control circuit controls variable or switchable capacitors or inductors. Alternatively, the oscillator is embodied as a VCO.

摘要： In einem ersten Aspekt der aktuellen Erfindung wird eine drahtlose Speiseschaltung vorgeschlagen, welche die Resonanzfrequenz eines LC-Schwingkreises elektronisch steuert. Eine Kapazität, eine Induktivität oder kombinierte Anordnungen von beiden werden mittels elektronischer Schalter während eines Teilintervals einer Netzwerkperiode zum Netzwerk gekoppelt. Ein Paar von weiteren Schaltern ist mit dem LC- Resonanzkreis gekoppelt und generiert darin eine kontinuierliche Schwingung.
In einem weiteren Aspet der Erfindung ist das Schalterpaar, welches die kontinuierliche Schwingung im Resonanzkreis generiert so mit dem Resonankreis gekoppelt, dass sich ein Oszillator ergibt.

摘要： A variable inductor structure for varying an inductance responsive to a digital tuning signal, comprising: a first inductor; a second, adjustable, inductor; and a digital control mechanism configured to receive the digital tuning signal and to adjust the effective inductance of the second inductor in response to the digital tuning signal; wherein the second inductor is positioned sufficiently close to the first inductor so as to be capable of altering by mutual inductance the effective inductance of the first inductor in dependence on the digital tuning signal.

摘要： A discrete inductive-capacitive (LC) filter selects between at least two inductor banks to tune the LC filter. The filter receives an input signal that includes one or more bands of frequencies. A control signal selects a band of frequencies for processing. A first inductor bank is selected to filter a first band of frequencies, and a second inductor bank is selected to filter a second band of frequencies. A switch circuit couples the input signal to either the first inductor bank or the second inductor bank. The switch circuit selects the first inductor bank if the first band of frequencies is selected, and selects the second inductor bank if the second band of frequencies is selected. The switch circuit electrically isolates the switching of the input signal to the first and the second inductor banks, so as to enhance the Q factor of the LC filter. Circuit and techniques are disclosed to reduce parasitic capacitance in a capacitive bank that employs MOS transistors. Furthermore, circuits and techniques are disclosed to tune a coupling factor on an inductive bank based on the frequency of the input signal.

摘要： A system for adaptive self-tuning of a receiver in a radio communcation systems. Prior to transmission of each data packet from a transmitter to a receiver, the transmitter generates a sequence of predefined test bytes (test sequence) n times at an initial carrier frequency. An identical version of the predefined test sequence is stored in the receiver. Circuitry is provided in the receiver for selected predefined states of tuning impedances for varying the centre operating frequency of the receiver, wherein the predefined states of tuning impedances are equal in number to the predefined number of test sequences. A microcontroller in the receiver compares the received test sequence with the stored test sequence and creates a tuning table correlating respective states of the receiver tuning impedances with error bits detected in each state. The microcontroller then selects the tuning impedance stat characterized by the least number of error bits, thereby selecting the optimal receiver centre operating frequency to the initial carrier frequency generated by the transmitter. After the data has been transmitted by the transmitter at the initial carrier frequency and received by the receiver at the optimal centre frequency, error detection is performed on the data. If the data has been received incorrectly, the transmitter changes its carrier frequency, the receiver changes its centre frequency correspondingly, and the adaptive tuning test sequence is repeated.
